"Su Wen's Theory of Four Temperaments Regulating the Spirit" says: "In winter and March, you must lie down early and get up late, and you must hold the sunlight." Go to bed early to nourish human yang and keep a warm body; Get up late to fix yin essence and do it at sunrise to avoid cold and seek warmth. In winter, most animals will go out less and hibernate. Therefore, in winter, we should have a regular schedule, sleep more, stay up less, improve yang, help healthy qi, and prevent the occurrence of "febrile diseases" in spring. "Spring grows, summer grows, autumn harvests and winter storage" are the natural laws of the four seasons. Living in nature, human beings must adapt to the changes of the four seasons and adjust their mental activities in order to achieve harmony between the human body and the surrounding environment, as well as the human spirit and physical function, so as to achieve the purpose of health preservation. "Su Wen Si Qi Tiao Shen Da Lun" points out the method of keeping in good health between the four seasons, that is, "In spring, heaven and earth are born, and everything is proud. People should lie down at night and get up early, so as to be ambitious, which is called keeping in good health; In summer, everything is gorgeous, and people should lie down at night and get up early, never be bored with the sun, so that they will have no anger. This is called raising a long life. The weather is urgent in autumn. People should lie down early and get up early, and be happy with chickens. This is called raising and harvesting: in winter, water and ice are on the ground, and there is no disturbance to the sun. People should lie down early and get up late, and they must wait for the sun, so that their aspirations will be subdued. This is called "raising Tibet", which embodies the principle of "raising yang in spring and summer, and nourishing yin in autumn and winter".

2. tonify kidney and spleen, and harmonize qi deficiency.

Kidney governs salty taste, while heart governs bitter taste. Winter diet should reduce salty taste and increase bitter taste, so as to replenish heart qi and consolidate kidney qi. Diet should be products that warm yang and protect yin, and avoid cold, sticky and hard food. Pay attention to reasonable collocation, and choose foods rich in iron (such as laver, tomatoes, mushrooms and fungus), foods rich in calcium (such as bean products, green beans, lotus root starch, rape, laver and milk powder), foods containing vitamin A (such as carrots, Chinese cabbage, a small amount of eggs and a small amount of liver) and foods rich in vitamin B2 (such as black beans, mushrooms and almonds). In addition, eating hot porridge in the morning and dieting at night are easy to nourish the stomach. Mutton porridge, glutinous rice, red dates, lily porridge and eight-treasure porridge, as well as Chinese medicines such as ginseng, astragalus root, donkey-hide gelatin, velvet antler, angelica root, etc.

3, adjust the mood, peace of mind

The ancient health-preserving theory emphasized that health-preserving is better than nurturing. The so-called cultivation mainly refers to moral cultivation, such as ideals, sentiments and spiritual life. The ancients believed that emotion is related to the function of human viscera. In The Great Theory of Su Wen Yin and Yang, it was pointed out that "anger hurts the liver, happiness hurts, thinking hurts the spleen, sadness hurts the lungs, and fear hurts the kidney", and six exogenous evils (wind, cold, summer heat, dampness, dryness and fire) and seven internal injuries (joy, anger, worry, thinking, sadness and sadness) are involved. Therefore, Neijing has repeatedly pointed out that "excessive cold and hot weather make life unstable", and repeatedly emphasized that "harmony with anger" is the way for wise people to keep healthy: in ancient health-keeping works, it is believed that the emotional activity center is everything, but actually it is advocated that people's reason and noble moral sentiments should dominate emotional activities, so it is necessary to get rid of selfish desires and distractions, maintain optimism, cheerful personality, noble sentiments, internal defense of spirit and unity of form and spirit.

4. Guided massage to enhance physical training.

There is the name of "guiding" and "pressing" in "On Different Methods and Appropriate Prescriptions". Guidance is an ancient medical gymnastics in China, which is mainly based on human muscle movement and cooperates with certain respiratory movement. It can not only keep healthy and strengthen the body, but also prevent diseases and treat diseases. Su Wen's Notes on Blood-gas Formation holds that guidance can cure "diseases born in tendons" and "stagnation". In ancient times, the contents of guiding included guiding (gymnastics), and later, Wuqin Opera, Tai Ji Chuan and so on. In Neijing, the word "pressing" was put forward for the first time. It is a kind of exercise in the form of massage, massage and tapping, which can not only preserve health, exercise, but also treat diseases and protect health. "The Great Theory of Su Wen's Four Temperaments Regulating the Spirit" requires people to "lie down at night and get up early, and walk widely in court", to exercise by long-term walking and running, to improve and promote the metabolism of organisms through human movement, so as to make various organ systems in the body full of vitality, enhance physical fitness and improve health. However, improper exercise will also be harmful to the human body, and proper exercise can be beneficial to the human body. Otherwise, "it will hurt blood for a long time, hurt gas for a long time, hurt meat for a long time, hurt bones for a long time, and hurt tendons for a long time."
